T 0 (6 whom it may concern:

Be it known that CHARLES P. KLoRER, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Sheet-Registering Devices, of which the following is a specification.

My invention relates to automatic devices for bringing sheets into register upon a supporting surface prior to a printing or kindred operation. 7

In printing, it is usual to provide the platen or other sheet-supporting surface with one or more end stops against which the end of the sheet abuts and with. one or more side stops against which a side of the sheet abuts. When the sheet engages against both the end and the side stops it is in correct register. Automatic devices have been heretotlore provided for bringing the sheets into such engagement with the end and side stops. it is .an object of my invention to improve generally upon devices of this character. It is another object of my invention to provide a register device in which means are provided for definitely retaining the sheetengaging member against movement at the time when it is receiving a sheet. Another object of my invention lies in the provision of a register device which will move the sheets with especial smoothness and ease and without marring the sheetssupporting surface. It is still a. further object ofmy invention to provide a sheet registering device capable of giving good registering results when used in connection with sheets varying within wide limits of size. Other objects will appear from the following SlJGCllir cation and claims.

As an example, I have described in the following specification, and shown in the accompanying drawings, one embodiment of my invention as applied to the platen of a job press. I wish it to be understood, however, that the invention may be embodied in other forms, and that changes may be made in the form described and shown, without exceeding the scope thereof, as defined. in the appended claims.

In the drawings:

F 1 is a plan of the platen of a job press, having a sheet register device constructed platen grippers being in their in accordance with my invention applied thereto:

Fig. 2 is an enlarged plan of the register device removed from the platen;

Fig. 3 is an elevation of the same;

Fig. 4 is a section 011 the line 4t-4 of Fig. 2, looking in the direction of the arrows, the platen grippers being in their raised position; 7

Fig. 5 is a section on the line 55 of Fig. 2. looking in the direction of the arrows, the closed position;

6 is a view showing the action of the register arm when a small sheet is to be registered; and

Fig. 7 is a similar view showing the action of the register arm when a large sheet is to be registered.

The register device is herein described as applied to the platen of a Gordon press. Such a press comprises a platen 10, mounted so as to be capable of being rocked into and out of ope alive relation with the type-bed of the press, having bails 11 for securing a tvinpan 12 thereo. A gripper bar 13 is mounted to rock in bearings carried by the platen and has grippers 14. connected therewith so as to be longitudinally adjustable thereof. Vhen the platen is near its printing position, the grippers ll pressdownwardly upon the sheet to be printed, the top of the gri per bar 13 being then substantially parallel with the surface of the tympan. hen, however, the platen is in'position or receiving the sheet, the grippers 14L are raised therefrom as indicated in dotted lines in Fig. 4:, the gripper bar being then rocked to a position in which its top is at an angle to the surface of the platen. To permit my improved register device to be applied, the gripper bar 13 has a portion of its lower front edge cut away, as at 15.

Y My improved register device comprises a base 16 having holes therein for the passage of studs 17. These studs upwardly through the platen and are threaded therein,

being provided with screw-driver slots 18 topermit vertical adjustment of the device. The base 16 engages against collars 19 on the studs and is secured in such engagement by nuts 20.

Extending upwardly from the base 16 is its upper end, the stem 24 is formed with acylindrical head 27 having a pin 28 forced there-through in such a manner that onehalf of the pin is located beneath the face of the head on one side of the latter, the pin being cut away on the opposite side. The top of the standard 21 is formed with a collar 29 which is cam-shaped on its upper surface, such surface sloping downward from the front to the rear and being formed at the center of the front with a depression 30 in which the projecting portion of the pin 28 normally lies, being held in such engagement by the spring 27 A to and fro rotating movement is imparted to the gear wheel25 by means of an arcuate rack 31 which is maintained in operative relation with the gear wheel by being passed through a guide groove 32 formed in a post 33 which extends downward from the base 16. The rack 31 is pivoted to a bracket 34 consisting of an upper and lower clamping member, which members embrace the rear side of the gripper bar 13 between them. It will be noted that as the gripper bar 13 rocks from the position shown in dotted lines in Fig. 4 to that shown in Fig. 5, the gear 25 and consequently the head 27 will be rotated in a clockwise direction, a contrary movementtaking place when the gripper bar returns to its former position.

Extending upward from the base 16 is a post 35 carrying at its top end a screw which passes through a slot 37 in an arm 38 extending from a plate 39. The plate is pivotally connected with the head 27 by means of a screw 40 disposed eccentric to the latter, and has secured thereto a leaf spring 41 having a slot 42 therein, said spring engaging against the under surface of the head of the screw 36. The leaf spring 41 operates to maintain the plate 39 against looseness or rocking on the head 27. At its end remote from the screw 36, the plate 39 is bent over to form a socket 43 for receiving the shank 44 of a sheet receiving register fork 45.

The operation of the device is as follows:

When a sheet, 46, is fed to the platen it will assume a position such as indicated in Fig. 1, engaging with its edge in the register fork 45. The grippers 14 are then raised, as indicated in Fig. 4. As the platen swings toward printing position, the gripper bar 13 begins to swing upward, thus, by means of the rack 31, causing the gear 25 and head 27 to rotate. The first effect of the rotation of the head 27 is to cause the pin 28 to ride up out of the depression 30, thereby raising the plate 39, register fork 45 and the sheet 46 engaged in the latter through a small distance. As the rotation of the head 27 continues, the register fork is caused to describe a curve downward and to the left, thereby bringing the sheet against the end register stops 47 and side register stop 48. The downward slope of the top surface of the collar 29 causes the register fork to be gradually lowered as it carries the sheet towards the stops. When the platen returns to sheet-- receiving position, the head 27 and register fork are brought back to the position indicated in Figs. 13, ready for another sheet.

The register device described above has several important advantages. One of these is that by the engagement of the pin 28 in the depression 30 of the register fork is held rigid, in spite of any looseness or play which might exist in the parts, during the time that it is receiving a sheet. This is a considerable'benefit, particularly when the device is being used with an automatic feeding mechanism, which would place the sheets on the platen with some speed and force. Another advantage lies in the ease and smoothness of the moving of the sheet which is obtained by slightly raising it off the tympan at the beginning of the registering movement. Another advantage lies in the fact that the register fork clears the paper after a relatively small lateral movement. The importance of this will readily be apparent from Fig. 6, which illustrates the use of the device in registering a small sheet. To register such a sheet the register fork will ordinarily need to have a long shank; yet it must clear the paper in a sufficiently small space to leave room for the register stop 47 at the lower left-hand side of the sheet. Thus the smallness the lateral movement of the register fork of my improved device enables sheets of smaller size to be registered thereby than would otherwise be convenient. lVhilst the register fork has a relatively small lateral movement when a long shank is being used, it still has sufficient movement properly to register a large sheet when a short shank is being used, as will be apparent from Fig. 7.
